Can you explain this using the rules I made for the game below

Rules 1.To start off this game you need 2 things a pair of 6 sided dice and another person to play with 2.The Rules of this game are simple to start off each person rolls one dice and the person who rolls the higher number starts 3. The person who rolled the higher number rolls the two dice and if they land a 7 or a 11 they instantly win if a person rolls a pair of 2s they instantly lose 4. Players keep playing until a 7,11 or a pair of 2s is rolled.
